The pattern matters more than one bad day
PMDD concerns usually require seeing timing over more than a single week. The record links mood, irritability, anxiety, sleep, energy, conflict, work impact, and cycle timing so the person can discuss repeated patterns with qualified care.
- Track symptoms by date.
- Mark how symptoms affected daily life.
- Look for repeated timing, not isolated proof.
Crisis moments need real support
If someone is having thoughts of self-harm, panic that feels unsafe, or a mental-health crisis, an app log is not the support plan. Use local emergency or crisis resources right away.
- You shouldn't wait for an app if there is danger.
- Use qualified mental-health support.
- Tell a trusted person if immediate help is needed.
Partner sharing needs care
A partner can help by understanding that mood symptoms may be time-linked and intense. They should not use the tracker to dismiss feelings as hormones or monitor someone without consent. Many people will do better sharing a summary or support preference than every mood entry.
- Share a summary if raw mood entries would create pressure.
- Share support preferences, such as space, fewer decisions, or a check-in later.
- Ask for specific support, not interpretation.
- You shouldn't let a partner label the person’s mood for them.
How to use the log well
Use the tracker to prepare a calm summary: when symptoms start, when they ease, what severity looks like, what helps, and what questions to ask a clinician.
- Track at least dates and impact.
- Note sleep and major stressors.
- Bring the pattern to qualified care.
Use prospective daily ratings instead of reconstructing the month
PMDD assessment depends on the relationship between symptoms and the menstrual cycle, so memory at the end of a difficult month is not enough. The Office on Women's Health says a symptom calendar or diary helps a doctor diagnose PMDD. Log at roughly the same time each day, including days when symptoms are absent. Track a small stable set such as depressed mood, anxiety, irritability, concentration, sleep, energy, physical symptoms, and functional impact. The symptom-free or lower-symptom interval matters as much as the difficult days because it helps show whether symptoms follow the cycle or persist throughout the month.
- Continue for at least two cycles if a clinician asks for prospective ratings; do not fill missing days from memory as though they were observed.
- Record treatment changes and major stressors without assuming either one explains the whole pattern.
- Use neutral descriptions of conflict or impairment instead of assigning blame to yourself or a partner.
- Take the completed daily record to a clinician who can consider PMDD alongside depression, anxiety, medication effects, and other possible causes.
- Choose ratings you can repeat even on difficult days; a short complete daily set is more useful than a detailed form abandoned during the symptomatic week.
- If symptoms include suicidal thoughts or immediate danger, stop tracking and contact local emergency or crisis support now. A predicted phase is never a safety assessment.
- Ask the clinician how to continue tracking after treatment begins so changes can be compared without treating the app score as the treatment decision.
- Record the first day of bleeding consistently so the symptom timeline can be aligned with the same cycle marker each month.
